Flyte The Hard Way

This tutorial walks you through setting up Flyte in a semi-automated way. It includes all the manual steps you need to prepare the infrastructure before adjusting and installing a Helm chart.
For a fast way to experience Flyte, try Union Serverless, a platform managed by Flyte's creators.

The steps described taken in this tutorial are not the only prescribed way to prepare the infrastructure or deploy Flyte. Feel free to contribute improvements or adapt it to your organization's policies and best practices.

This guides takes inspiration from Kubernetes The Hard Way

Target audience

This tutorial is intended for platform/infrastructure engineers who plan to support a Flyte environment for production or testing.

Introduction

Flyte is a flexible and robust platform to develop and deploy machine learning workloads in a cloud-native environment. It facilitates interaction with the underlying Kubernetes infrastructure for users who are not entirely familiar with it.

To make Flyte work (especially for deployment), you’ll need to prepare the infrastructure layer.

While the official documentation covers the general process to deploy the single binary version, this tutorial aims to supplement docs with guidance to prepare the for a successful installation of Flyte.

Flyte on AWS

This tutorial will deploy Flyte single binary to an EKS environment, progressively adding features to reach a production-ready setup.

For the purposes of this basic tutorial, I adhered to the following principles:

Keep all Flyte components in the same VPC
Use default permissions when needed. More fine-grained access control can be defined and implemented by each organization
Tag resources in accordance with your DevOps policies
Deploy no SSL or Ingress. Follow parts 2 and 3 of this series to add those features

Part I: Simple deployment without SSL, Ingress or authentication

Lab 1: Configuring permissions on AWS
Lab 2: Deploying an EKS cluster
Lab 3: Configure roles and service accounts
Lab 4: Create a relational database
Lab 5: Deploy with Helm

Part II: Scalable networking with Ingress

Lab 6: Intro to Ingress and configuring the controller
Lab 7: Configure SSL
Lab 8: Adjust Helm values and upgrade the release
Lab 9: Connect to Flyte through Ingress

Part III: Securing the stack with authentication

Lab 10: Prepare your environment for auth using Okta
Lab 11: Upgrade your Helm release to use auth

Flyte on local Kubernetes

In the following tutorials, you'll deploy the flyte-binary chart to different Kubernetes distributions running on-premises.

microk8s on VMs or bare-metal

Part I: Single node without Ingress

Lab 1: Deploy an on-prem K8s node
Lab 2: Configure dependencies and install Flyte

Part II: Multiple worker nodes and Ingress (coming soon)

Part III: Auth (coming soon)

microk8s on Raspberry Pi

Part I: Simple deployment with no Ingress or auth

Lab 1: Prepare a Raspberry Pi for microk8s
Lab 2: Install & Configure microk8s
Lab 3: Install Minio & Postgres
Lab 4: Install Flyte

Part II: Adding Ingress, TLS & submitting workflows

Lab 5: Adding Ingress and TLS
Lab 6: Submitting Workflows

Part III: Adding Flyte Task Logs & Auth

Lab 7: Adding Flyte Task Logs

Flyte deployment options

Hosted sandbox is available for free at sandbox.union.ai for a maximum of 4 hours. It includes a VS Code environment, Jupyter notebook and UI ready to get a quick feel of the platform.
Sandbox deploys a local, minimal Flyte backend via a single command. It includes core services, but it doesn’t scale and supports only the necessary extensions to expose the core Flyte functionality.
Single binary bundles console, admin, data-catalog and propeller services within a single binary that can be deployed to a production K8s environment or to a local test setup such as minikube. It uses a single Helm chart to reduce startup times and simplify deployment.
Core is the fully fledged deployment with complete control over the configuration of each Flyte component, including production-grade features like federated authentication and Ingress networking.
